What is the valve under left back slide for? kitchen grey water? How do you drain the fresh water tank?

[boat391]

Yes the valve is for galley tank drain. As for fresh water tank drain look under left rear of your trailer should have a hose hanging down with a white cap on it unscrew this cap and tank will drain. Hope this helps.

Some of us have replaced the screw on cap on the fresh water for a valve that you can just twist open or shut.

You will find out REAL FAST what it is for ,I had a 3402RL and yes it is the Galley tank drain it fills up pretty quick when you are a fulltimer like us, and and like boat391 said you will see a hose hanging down with a white cap and that is the drain for the fresh water tank
